Subject: [PATCH] allow to change User Agent; fix levmar download

Parameter $(PKG)_UA overrides default user agent used by wget to download
a package. It is needed, because download server www.ics.forth.gr from where
levmar is downloaded, crashes on default user agent Wget/1.13.4.
User agent for levmar was set to MXE. Now the server works.
